About the venue

Alma Mater Chiloniensis, Kiel's university, was founded with a ceremony at Nikolaikirche (Church of St Nicholas) on Monday, 5 October 1665. Soon after, the university took on the name of its founder and has since been known as Christian-Albrechts-Universität zu Kiel (CAU). The number of students at the university is approximately 24 000, and the range of subjects offered cover economics, the natural sciences, agriculture, engineering, and science of education. In the former workplace of Max Planck and Heinrich Hertz, a teaching staff of 600 passes on their knowledge to students from Germany and more than a hundred other countries. The lectures will take place at the physics department.


Kiel is the state capital of Schleswig-Holstein, the northernmost state of Germany, between Denmark and Hamburg. Schleswig-Holstein is the land between the seas, it is located between the North Sea and the Baltic Sea. Kiel is at the east end of the Kiel Canal, the world's busiest artificial waterway, which connects the Baltic Sea with the North Sea. As a major harbor, Kiel is the home of the Gorch Fock, a tall ship of the German Navy.

Kiel is also the home of the largest sailing event in the world, the Kieler Woche which takes place every year at the end of June.

Besides sailing (Olympic Games 1936 and 1972), Kiel is also famous for Handball (German record Champion THW Kiel), soccer (German Champion 1912 Holstein Kiel), football (German Champion 2010), smoked fish (Kieler Sprotten) and the uniform of D. Duck (Kieler Anzug).

Understanding Solar Eruptions and Extreme Space Weather Events – The physics behind
HESPERIA Summer school
August 29, 2016 to September 2, 2016
Christian-Albrechts-Universität, Kiel, Germany


The Sun is both a source of all life and significant hazards. Solar energetic particle (SEP) events provoke extreme space weather. While not noticeable by humans on Earth, space weather caused radiation is a hazard for satellites, for the astronauts onboard the International Space Station (ISS), and in extreme cases for the aircrew on polar flights. But energetic particles are also of general astrophysical interest. Supernova remnants, pulsars, active galactic nuclei can only be seen because these objects accelerate particles. So does the Sun. Solar particles can not only be observed through their electromagnetic emission, but they can also be directly measured in space as SEP events and in extreme cases as ground level enhancements. We see their time evolution and can use it to constrain the acceleration processes. Therefore, scientists observe SEP events and incorporate methods to know or even forecast the radiation hazard associated with them.

Educational Objectives

The HESPERIA course at the Christian-Albrechts-Universität provides an introduction to the physics of the active corona, the variable solar wind including the interplanetary field embedded in, the acceleration and transport of energetic particles as well as their transport through the Earth magneto- and atmosphere and radiation effects. The lectures include a variety of interesting phenomena observed on the Sun and in interplanetary space.


Students will attend a variety of lectures on space physics and research topics related to space weather and will gain valuable hands-on experience under the mentorship of a HESPERIA scientist. This program also provides students with opportunities to develop their written communication skills, by presenting their research in a formal report at the end of the summer school.


The school is open to 25 graduate students currently enrolled in astro or space physics, planetary sciences, space engineering or a related field. Program acceptance is based primarily on the student’s academic record and nomination letter. Acceptance will also be based on the student's interest in attending the summer school and the benefit to the student of attendance, as demonstrated in the cover letter.
